The U.S. Government Printing Office (GPO) has announced the development and hosting of new Persistent URL (PURL) architecture by Zepheira. GPO’s PURL service provides persistent Web addresses for critical government documents and is primarily used by the more than 1,200 Federal Depository Libraries. GPO PURLs are open to members of the public. Read more
The National Center for Biomedical Ontology and Zepheira are pleased to announce work on a PURL Federation. A PURL Federation will allow multiple PURL service operators to cooperate in PURL resolutions, covering for each other in the case of service outages and allowing the persistent resolution of PURLs as funding levels and organizational details change with time.

On July 27, 2009 OCLC upgraded their PURL server to a new open source platform built by Zepheira. PURLs are Web addresses or Uniform Resource Locators (URLs) that act as permanent identifiers in the face of a dynamic and changing Web infrastructure. OCLC’s upgrade reflects their continued support to provide persistent, stable World Wide Web (WWW) addresses for the international library and education community, government, business, and non-profit organizations, and private citizens. OCLC’s PURL server currently resolves approximately two million PURLs per day. Read more
PURL Server version 1.5 has been released and is recommended for all PURL server operators.
Version 1.5 of the PURL server subtly changes the relationship between PURLs and domains to better support legacy PURLs. Domains may now be created that contain PURLs of the same name (that is, a PURL with a name corresponding to an empty string or a ‘/’ character).
The PURLZ Persistent URL Server version 1.4 is now available. See the PURLZ Downloads area to get your copy now. This release improves handling of URLs with query strings and special characters. It is recommended for immediate use by all PURL server operators. PURLs are Web addresses or Uniform Resource Locators (URLs) that act as permanent identifiers in the face of a dynamic and changing Web infrastructure. This capability provides continuity of references to network resources that may migrate from machine to machine for business, social or technical reasons. Details are available on the PURLZ community site. Please see also the README and Release Notes for version 1.4.
A legacy loader is available to take old OCLC version 1 Persistent URL (PURL) database dumps and upload PURLs into the new project‘s RESTful API. This is not production code, but is provided in the hope that it may be useful to operators of old PURL servers wishing to migrate to a more modern PURL server. The legacy loader has been released under an Apache 2.0 license. To get the legacy loader, use Subversion to check it out like this:
svn co http://purlz.zepheira.com/svn/purlz/purlsbulkloader
Check out the code and follow the directions in the file README.txt. This information is also available at the PURL PURL Project’s Download Area .
